Summary
Effervescent aspirin products deliver analgesic doses of salicylate that can enhance the hypoglycemic effect of gliclazide. Hypoglycemia may occur, particularly with repeated dosing or reduced renal function.
What this interaction means in plain words
Aspirin / citric acid / sodium bicarbonate and Gliclazide can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Salicylate has intrinsic glucose-lowering activity and may displace sulfonylureas from plasma proteins, giving additive hypoglycemia.
What to do
Monitor blood glucose when salicylate use is regular or at high dose and reduce gliclazide if hypoglycemia develops. Advise the patient to report symptoms of low glucose.
